Electric drive apparatus

An electric drive apparatus comprising:

• a rotating electric machine including a rotor, a stator and a housing, the rotor being provided on a rotating shaft so as to rotate together with the rotating shaft, the stator including an annular stator core and a multi-phase stator coil, the housing having both the rotor and the stator received therein;
• and
• a transmission including a motive power transmitting unit that is configured to rotate with rotation of the rotating shaft,
• wherein
• the transmission is provided, on one side of the rotating electric machine in an axial direction of the rotating shaft, integrally with the rotating electric machine,
• the stator coil is assembled to the stator core to have first and second coil end parts respectively protruding from first and second axial end faces of the stator core,
• an axial protruding height of the second coil end part from the second axial end face of the stator core is larger than an axial protruding height of the first coil end part from the first axial end face of the stator core,
• the first coil end part is located on a same axial side of the stator core as the transmission and the second coil end part is located on an opposite axial side of the stator core to the transmission,
• there are provided, on the same axial side of the stator core as the second coil end part, busbars through each of which electric power is inputted to and outputted from one of a plurality of phase windings of the stator coil,
• the housing of the rotating electric machine has a covering part arranged to cover the second coil end part, and
• in the covering part of the housing, there is formed a through-hole through which each of the busbars or a terminal member connected with the busbars extends from an inside to an outside of the housing.
